Tru Tech Amps

I'm not familliar with TRU's more recent amplifiers, but I'm sure their 'preamp cards' either directly affect the signal or at least have different features... if you want to compare the gain block section of the amps, I can assure you a TRU will not sound different from a JBL....

To say that the gain block section of a JBL versus a TRU will sound the same is a bit suspect to me. It seems you accept that the pre-amp section could affect the final sound of the amplifier. If the pre-amp section can affect the sound then most certainly the final gain stage/output stage can affect the sound of the amplifier.
Why would amplifiers not sound different?
An amplifer designed with class A topology will sound different than class A/B or class D topology. A bipolar output transistor has different characteristics than a Mosfet, therefore will sound different.
There a number of factors that can effect the sound of an amplifier. One is the parts used. Another is the topology. Another is the designers skill and design goals. You can drastically change the sound of an amplifier by increasing or decreasing the bias a few millivolts.
Most products do sound different from each other. I am not sure you can make blanket statements that one product sounds better than another. There is so many variables in how a system sounds. Source, cables, amps & speakers and vehicle acoustics all affect the sound. Some people do not know how to listen critically and others just do not have the 'ear' to hear differences that others others do. We all hear different. Another important aspect is psycho-acoustics. They play a huge part in what we hear.
I am sure some JBL amps can sound great in some systems. I am also sure that some TRU amps can sound like **** in some systems.
yada yada yada

this is the best thing on this post about amps
hey if i had a car that i was going to keep and had the $ i would run silver speaker wire

You should embrace and roll with your last sentance there.... and maybe refer to some ABX testing between amplifiers...

you might be catching on, lets take two identical amplifiers and flip the bass boost for one amp on.... the preamp section just made that amplifier sound different from the other....
I am quite sure that 7-Z's is heavilly medicated and probably believes in all sorts of non-sense... since you seem to believe the same I can assure you that you are wrong....

Hey, OK I get it, you think all amps sound the same. You are entitled to your opinion. It does not mean that you are right except for in your own mind. I don't care if you don't believe what I believe either. You might just be one of those people that cannot hear the difference. I can, it has taken me years to learn to listen critically to audio, and I'm not talking in the car because the car is not even close to an optimal environment for audio reproduction.
